SPECIFICATION forming part of Letters Patent No. 243,084, dated June 21, 1881. Application filed January 28, 188]. (No model.)

To all whom it may concern Be it known that We, WILBER S. SALIsBURY and WILLIAM ARMSTRONG, o f Chicago7 Illinois, have invented a new and useful Portable Oollapsing Boat, of which the following is a specification.

Our invention relates to improvements in portable collapsing boats in which vertical adjustable stem-timbers and horizontal gunwale and bilge timbers with removable seats, arranged with extension-.legs and removable sectional keel-boards, operate in conjunction With a flexible skin or cloth covering; and the objects of our improvements are, first, to provide adjustable stems; second, to afford facilities for the proper adjustment of the seat-legs independent of each other in respect to the keelboards; third, to make longitudinal timbers in sections, to lnore readily facilitate the collapsing and carrying; and, fourth, to provide a skin or covering of ieXible material, so arranged as to be readily attachedl or removed from thetimbers. We attain these objects by the mechanism illustrated in the accompanying drawings, in Which- Figure 1 isa top view of the boat as it appears set up, and with sections of the seats removed to show the plan of fastening the keelboards. Fig. 2 is a vertical sectional view of the boat from end to end. Fig. 3 is a vertical cross-section amidships. Fig. 4 is a vert-ical end section enlarged. Fig. 5 is a section showing the manner of lacing the skin to the gunwales. Fig. 6 is a vertical section of the end seat-s.- Fig. 7 shows detail views of the hinged extension-legs.

Similar letters refer to similar parts throughout the several views.

A AA A are the gunWale-timbers, made in sections. B B B Bare the bilge-timbers, made in sections. O C C C are ferrules upon the gun wale and bilge timbers. DD are stationary stems, to which the gnnwale and bilge timbers are secured by means of an iron-bar connection. are provided withnuts and screw-bolts, FF F F. f f are loose nuts on the screw-bolts. F F F F are screw-bolts passing through stem-timbers D D. G G Gr G are hook-clasps attached to the gunwale-timbers H El H H, chains and hooks attached to the seats; I l I I, brace- E E are movable stem-posts, and

nuts L L L, extensionpieces attached to seatleg; M M M M, gunwale-lacing for attaching the skin to timbers; N N N N, keel-boardsin sections connecting under each seat; O O 0, hatten-strips on keel-boards. l) P P and RR R are bars and sockets for connecting keelboards; S S S, bolts for extension-piece on legs; T T, leather strap and buckle to prevent leg from tripping; U U, brace-clips. (See Fig. 3.) V V V V are staples, ferrule, and eyebolt for connecting gunwale and bilge timbers to stem-timbers; V WV, stem-rope fastening, made fast to skin and eyebolt X Y Y, nuts for receiving end ofscrew-bolt; Z Z, skin or covering, Without seam in bottom a', hatten-blocks on end of keel-board, and b amidships.

To set the boat up, .we rst connect the gunwale and bilge timbers (which are numbered) with the ferrules. The frame is then placed in the skin. Then fasten the rope on each end ot' the skin to the eyebolt in stems E E. Next proceed to lace the loops attached to skin bypassing each loop over the gunwale timbers, then through the eyelet, and proceed to lace one loop into the other from end to end, as shown in Fig. 6, and fasten the last loop with a half-hitch. The small seats J J are pushed into the notch in the brace-timbers, and the chains on the seats are hooked into the clasps on the gunwale, which lock them fast. The keel-boards are then put into position and held there by pushing the bars'into the sockets R R. Then the hinged legs are forced down upon thekeel-boards. Then buckle the strap which keeps the leg from tripping. (The keel-boards are so arranged that the joints of each section of the same come under the center of each leg of the seats.) The center seat is put in last and locked with the chains to the gunwale-clasps, the hinged legs forced down to blocks b b. Y The strap is then buckled7 thus completing the settn g up of the boat.

To make up inte a sectional package, unbuckle the straps first. Then close the legs and unhook the chains. Take out the middle seat IOO rst. Now remove the keel-boards and then the small seats. Then proceed to undo the lacing and unhitch the rope from eyebolt at the stems. Then remove the frame from the skin. The timbers can now be unferruled and the frame made into a package.

To collapse the boat into a full-length package, remove the keel-boards and seat-spreaders, as previously set forth. The sides then come together, making a tlat package the full length ot' boat, in which can be stored the seats and keel-boards edgewise, making a convenient package for portage, storage, and shipment. p y

An important feature, should the skin be.- come slack through use, is to tighten it longitudinally by the screws at each end and vertically by the means of the extensionlegs, letting out one or more holes, as required, thus always keeping the skin smooth and taut.

What We claim as our invention, and desire to secure by Letters Patent, is-

1. The combination, in portable boats, of sectional gunwale and bilge timbers, connected by braces I I and fastened to stem-timbers D D, operating in conjunction with the movable stems E E and spreaders J J J, keel-boards N N, and skin Z Z, all substantially as set forth.

2. In a portable boat having a exible skin, the movable stem-posts E E, provided with screw-bolts F F F F, passing through station- 'ary stems D D, for the purpose of longitudinal adjustment of the flexible skin, in combination with the spreaders H I-I and extensible hinged legs K K, affording crosswise adjustment, all substantially as set forth and described.

3. In portable boats, the combination of seats J J J, as Shapers and spreaders, providedvith chains and hooks H H, hinged extension-legs K K K, and buckle-straps T T, all substantially as set forth.
